City version, no more confusion

Hi Guys
To avoid confusion, We will slowly remove the BJ and TP version in Mandarin class.
In the future, when you book a simplified Mandarin class, you will be taught by Shang Hai version.
We will create another language called Mandarin traditional so anyone who loves to learn traditional character can book these classes. TP will be the city version for Mandarin traditional.
Hope that will help
